Out-of-band biometric enrollment and verification using interactive messaging

ABSTRACT

A system and method for enabling out of band biometric verification is disclosed. The system includes a biometric engine coupled with an interactive messaging system and configured as an identity provider. The biometric identity provider includes a biometric enrollment process using open standard authentication protocols. The identity provider may answer calls generated by a service provider for biometric verification request for a user by sending an interactive message to a wireless mobile device associated to the user. The user captures and sends a biometric input to the identity provider. Biometrics provided by a user are compared by the biometric engine against biometric templates stored for that user in order to verify the user. The identity provider then sends a response back to the service provider. The service provider may grant or deny services to a user depending on the response.

BACKGROUND OF THE INVENTION 1. Field of Invention

The present invention relates generally to identity management and more particularly, to a technique for out-of-band biometric enrollment and verification using interactive messaging.

2. Description of Related Art

Many users of the Internet utilize web-based email applications, online services, social networking sites, and other websites that require authentication of the user. Systems for logging in to websites via a user name and password have been implemented across many websites. At times, a single user may have many login credentials for numerous different websites that the user may visit. For example, a user may have many email accounts from different email providers or a user may have different login credentials including passwords for accessing various online services from different banks. Typically, users like to have different passwords for different accounts so that if one password becomes compromised, then all passwords will not be compromised. Using multiple login identities may become troublesome for the user because a user may forget or confuse login credentials from the different online service sites.

Single sign-on (SSO) technology permits access control of multiple related, but independent computer systems. A user logs in once to an identity provider to gain access to online services from multiple disparate service providers without using different usernames or passwords. However, SSO technology poses a security risk if an imposter steals or discovers the SSO login credentials and gains access to all the online services and independent computer systems.

Biometrics is a generic term for characteristics that can be used to distinguish one individual from another, particularly through the use of digital equipment. An example of a biometric is a fingerprint. Trained analysts have long been able to match fingerprints in order to identify individuals. More recently, computer systems have been developed to match fingerprints automatically. Examples of biometrics that have been, or are now being, used to identify, or authenticate the identity of individuals include face (2D or 3D), hand geometry, fingerprint, finger geometry, iris, finger vein, retina, DNA (using segments from DNA), ear, odor, palm, gait, signature, and voice among others, the implementation of which are apparent to one of ordinary skill in the art.

Biometric authentication increases security and enables a user's identity to be validated without the user having to remember a user name and password. It is desirable to incorporate biometric authentication as an identity provider service to access multiple online services.

SUMMARY OF THE INVENTION

The present invention overcomes these and other deficiencies of the prior art by providing an integrated system combining operations of an interactive messaging system with a biometric engine in order to enhance security for a single sign-on identity provider.

According to an embodiment of the invention, an integrated system comprises an interactive messaging system operatively coupled with a biometric engine through a communications network connection such as the Internet. This integrated system also includes one or more online service providers. A biometric authentication service in communication with or incorporated within the interactive messaging system coordinates communication between the biometric engine and the interactive messaging system.

The present invention implements an application framework that allows interactive communication with one or more interactive messaging senders. This application framework includes data services, messaging services, brokering services, learning services, and biometric authentication services among others. Services in the application framework are used by a sender application which may configure, manage, send or push interactive messages to one or more mobile devices. Interactive messages may include a request for biometric enrollment along with corresponding action options that can be selected by the user when the user receives the interactive message. The mobile devices are capable of receiving or responding to interactive messages, as well as capturing one or more types of biometrics, e.g., face, finger, iris, and/or voice. The biometric engine may be coupled to or include a query router and may be operative coupled to one or more biometric data caches, which store biometric templates.

In an embodiment of the invention, a single sign-on identity provider enrolls a user using one or more biometric modalities. The user is a client of an online service provider such as a bank. The online service provider requests the identity provider to authenticate the user. The identity provider, by means of a server, checks if the user is already enrolled in the identity provider's biometric database. If not, the online service provider, by means of a server, requests user information via an interactive message to the user's mobile device and subsequently submits the user information through the identity provider to a biometric engine. The biometric engine adds the user information to its database or cache. The biometric engine then sends an e-mail, interactive message, or notification to the user with instructions for downloading and using a biometric authentication application. The user, by means of a mobile device, downloads and runs the biometric authentication application. The user enters into the application a preferred user name and password. A request is sent to the user's mobile device to capture one or more biometric probes. The user then employs the mobile device to submit the biometric probes to the biometric engine for enrollment where they are converted into biometric templates. The biometric engine enrolls the submitted biometrics, registers the user's device where the application has been installed, and associates the biometric templates and device with the user.

In an embodiment of the invention, a verification process within the integrated system begins when a service provider requests a user to be biometrically authenticated by the identity provider. The interactive messaging system determines the preferred conditions for biometric authentication. The interactive messaging system sends an interactive message requesting the capture of suitable biometric probes. A user responds by sending one or more biometric probes to the interactive messaging system, which subsequently sends those biometric probes to the biometric engine for verification. Query router within the biometric engine distributes the biometric probes to corresponding query engines, which compare the biometric probes against biometric templates already stored in the biometric data caches. The result of this comparison may be a score which indicates a probability of successful biometric matching. Biometric engine notifies a successful or failed biometric verification to the service provider which may subsequently deny or authorize the transaction. The interactive messaging system sends another interactive message to notify the user of a success or failure and may also include options for additional action to continue or conclude the verification process.

The present invention incorporates biometric authentication into interactive messaging, thereby, providing clients with secure and reliable transactions or communications. The present invention biometrically enrolls a client for later verification and identification services. In addition, the present invention combines the capabilities of both an interactive messaging service and biometric engine, including interactive communication, multimodal biometric operation, and situational support among others.

The foregoing, and other features and advantages of the invention, will be apparent from the following, more particular description of the preferred embodiments of the invention, the accompanying drawings, and the claims.

In an embodiment of the invention, an instant messaging system and one or more biometric engines are employed to allow the association of biometric probes and devices with clients upon registration into an authorized database of users of an identity provider.

FIG. 1 illustrates a biometric engine 100 according to an embodiment of the invention. Biometric engine 100 comprises a query router 102, one or more query engines 104, and one or more biometric data caches 106 associated with each query engine 104. Query router 102, although optional, is operatively connected to a suitable network connection 108, the identification and implementation of which is apparent to one of ordinary skill in the art. For example, network connection 108 can comprise a local area network (LAN), a virtual private network (VPN), a wireless area network (WAN), or any combination thereof to communicate to an interactive messaging system service via the Internet. Network connection 108 provides an operational connection with a client or a service provider that may use the biometric engine 100 as an identity provider.

Query router 102 includes software programmed according to the embodiments described herein and executed on a processor. Query router 102 can be associated with an optional demographic database 110 for storing demographic data, such as gender, age, or even personal information, such as name and telephone number, among others, of a client. The identification and implementation of the demographic database 110 is apparent to one of ordinary skill in the art. In another embodiment, demographic database 108 may be operated from a service provider infrastructure, in which case, biometric engine 100 does not directly associate the demographic data with biometric data when performing biometric authentication, thereby allowing anonymous biometric authentication through the use of tokens that can be used to isolate the specific biometric data for matching and/or analysis.

The demographic database 110 (and any other database discussed herein) may implement a database management systems (DBMS) such as, but not limited MySQL, PostgreSQL, SQLite, Microsoft SQL Server, Microsoft Access, Oracle, SAP, dBASE, FoxPro, IBM DB2, LibreOffice Base, FileMaker Pro, MongoDb, and/or any other type of database software that organizes collections of data.

Query router 102 is in communication with one or more query engines 104 through a suitable computer network, the identification and implementation of which is apparent to one of ordinary skill in the art. In an embodiment of the invention, each query engine 104 is implemented on a computer having installed thereon a suitable operating and biometric software according to the embodiments described herein. All query engines 104 can be implemented on the same computer or distributed among multiple computers. Each query engine 104 is associated with a biometric data cache 106, the implementation of which is also apparent to one of ordinary skill in the art. Each query engine 104 can be adapted to process a single biometric modality or multiple biometric modalities. In an embodiment of the invention, query engines 104 convert biometric data into templates for storage in biometric data cache 106 at enrollment. In another embodiment of the invention, the query engines 104 receive biometric templates created elsewhere, for example, from a biometric capture device. The query engines 104 create (or receive) biometric probes to compare against enrolled biometric templates at verification time.

In operation, query router 102 receives a call, such as a service-oriented architecture (SOA) call, from a client's device or a server associated with a service provider to verify the authenticity of a client's identity. The call includes user information that may be used by the biometric engine 100 to authenticate the biometric client. Information provided in the call may include, for example, demographic information, such as age, gender, city, and the like; or personal information, such as a name, a username, an email, a phone, or any information associated with the user that may be used by the biometric engine 100 for authentication. Alternatively, the call may be anonymous, i.e., without knowledge of biographic, demographic or otherwise identifying information. Information provided may also include a biometric probe that is to be compared against biometric templates previously stored in the biometric data caches 106. Query router 102 may route requests to the appropriate query engines 104, depending on the biometric type or work load on the query engines 104. Query router 102 monitors the activities of the query engines 104 and may combine their responses (success/fail) into a single SOA response that may be sent back to the client's device or service provider.

FIG. 2 illustrates an interactive messaging system (IMS) 200 according to an embodiment of the invention. IMS 200 comprises an application framework 202 for allowing communication with clients, both senders and recipients, by sending or pushing interactive messages to the client's mobile devices. In an embodiment of the invention, messages may be composed by filling in a pre-formed template. The application framework 202 pushes the messages to one or more carriers 204, which are connected to the application framework 202 via a network connection 206. The messages are sent to the mobile devices. Although four carriers are shown, any number (N) of carriers may be connected to the application framework 202. A messaging protocol on the application framework 202 allows both local applications 208 and outside or third party applications 210 to talk to core services. Services, located on the application framework 202 facilitate the delivery of messages by providing essential details and information that the application framework 202 uses to send or push the messages to mobile devices. Exemplary services as part of application framework 202 include one or more data services 212, one or more messaging services 214, one or more brokering services 216, one or more learning services 218, and one or more biometric authentication services 220, although additional services may be defined and utilized. The services are enabled via web services 222.

In one exemplary embodiment of the invention, learning services 218 are used to facilitate learning by sending or pushing study material, such as in the form of multiple choice questions, to recipients, such as students, among others. For example, vocabulary questions can be sent to the recipient when studying for the SAT. A word with four possible definitions can be pushed to the student's wireless device. Learning services 218 accomplish this managing a process for the user in order to learn new information, including concept presentation pre-testing, mastery drilling, final testing, and follow up review. Furthermore, learning services 218 allow external application and third parties to add data or additional learning curriculum to learning modules stored in learning services 218. Learning services 218 can also report on learning status by user and by curriculum module. Additionally, learning service 218 can also present curriculum to users in a game context wherein players compete on response time and accuracy.

Data services 212 store information, including profiles of users, which may be used to determine if and when an interactive message is to be sent to the recipient. Information stored within the profiles can include an access control list that filters or blocks specific senders, photographs, and sounds which might be included in a message and/or a do not disturb window specifying when the recipient does not want to be disturbed with an interactive message. Additional information in the profiles can include a priority profile where the user specifies the level of intrusion for receiving an interactive message (e.g., do not interrupt if on a call) and/or an ID, password information, and/or frequently used responses to be included in a message, a list of birthdays and anniversaries of friends and family and other holidays, among others. Other information, such as pending messages and system information can be stored in data services 212. Furthermore, data services 212 can store learning profiles for storing user progress across learning modules and learning module setup, learning curriculum and responses. Each user creates a profile and stores the profile on a database 224 located on the application framework 202. Other information contained in a profile can include a list of people whose messages should be immediately sent, and a picture of the user and times when a user does not want to receive a message. The profiles can be accessed through a web portal 226 allowing senders and recipients to update information from their profile.

Database 224 is implemented through a database management systems (DBMS), such as, for example, MySQL, PostgreSQL, SQLite, Microsoft SQL Server, Microsoft Access, Oracle, SAP, dBASE, FoxPro, IBM DB2, LibreOffice Base, FileMaker Pro, and/or any other type of database that organizes collections of data. Database 224 is used to store data, information, and rules for pushing the interactive messages to a mobile device. The database 224 can comprise user preferences, photographs, sounds, drop down menus, learning curriculum, birthday anniversary lists, and other holidays, among others.

Messaging services 214 pushes or sends an interactive message to the mobile device of a client. Before the message can be pushed, messaging services 214 first determines if the client's mobile device is capable of receiving a pushed message. If the mobile device is capable of receiving the message, messaging services 214 converts the message into a format readable by the mobile device and, in turn, pushes the message to the mobile devices. If the mobile device is not capable of receiving a pushed message, messaging services 214 converts the message to an instant message via short message service (SMS) or multimedia message service (MIMS) message, or a proprietary instant messaging service such as, but not limited to BlackBerry Messenger (BBM), Google Chat, or Skype for Mobile. Furthermore, messaging services 214, if necessary, is capable of formatting the message into a format that includes multimedia capabilities, such as text, sound, graphics, video, or a turn based interactive game, among others. Messaging services 214 also have the capability of providing the sender with a status of the message, e.g., if the recipient has responded and what the response is. The status of the message can be delivered to the sender with electronic data exchange, e-mail, instant messaging, on-line access (e.g., check the status via a web site), and WAP Push, including BREW and J2ME(JAVA), among others.

Brokering services 216 manage the coordination of clients, both senders and recipients, and the delivery of messages to mobile devices. Senders can specify a day and time for the messages to be delivered to the recipients. Senders can include both people and devices/servers. Recipients can have the option of rescheduling the response of messages to their wireless devices by selecting a “snooze” feature. The “snooze” feature terminates the interactive message and schedule a future time when the message can be resent to the recipient. Once this feature is selected, brokering services 216 resend the message at a later time, such as in 10 minutes, 30 minutes, an hour, or any other time specified by the recipient. Brokering services 216 also manages the level of intrusion of the message based on receiver maintained profile criteria via web portal 226 with settings by originator, data type, priority, and access control list.

The biometric authentication services 220 are used to facilitate biometric data exchange between senders and receivers. A sender can configure a message including the request for a biometric capture in order to perform different actions, such as to authenticate and authorize a client. Biometric authentication services 220 push or send an interactive message requesting a biometric input from a client. Before the message can be pushed, biometric authentication services 220 determine what biometric modalities are supported by the client or clients. Biometric authentication services 220 manage and store biometric information from the different client devices in their respective profiles, which in turn are stored in database 224. Biometric information stored in user profiles includes a list of biometric modalities supported by the mobile device of the client as well as statistical information of biometric push messages sent to the client. Receiver profiles are managed through web portal 226.

Biometric authentication services 220 manage and store sender profiles. Sender profiles include a list of supported biometric modalities as well as rules for biometric requests depending on the actions to be performed. For example, if a client wants to access a bank account, the sender may require more than one biometric modality for authentication in order to increase security, therefore, a push message requesting multiple biometric modalities may be sent to a client. Web portal 226 also includes options for a sender to manage their profile.

Biometric authentication services 220 receive a response to a push method that includes biometric probes captured by the client's mobile device. Biometric authentication services 220 is capable of providing the sender with a status of the request sent to the client, e.g., if the client has responded to the request as well as to transfer the biometric probe sent by the client to the sender. Biometric authentication services 220 may answer request calls sent by a biometric engine, such as the one described in FIG. 1. Biometric authentication services 220 may request a biometric probe through a push message, which is then sent by the biometric authentication services 220 to a biometric engine for matching. Biometric authentication services 220 also provide the receiver with a status message of their biometric matching results.

Application framework 202 employs application logic to define how the business policies, rules, and required services of the interactive messaging system of the present invention function. Local applications 208 store the application logic, call web services 222 using SOAP messaging 228, and instruct or trigger the construction and delivery of the interactive messages. Web services 222 share business logic, data, and process through a programmatic interface across a network amongst the different services. Since web services 222 may not be tied to any one operating system or programming language, different applications from different sources can communicate with each other without time consuming custom coding since all communications can be formatted in XML. As a result, web services 222 provide a platform for exposing or making accessible the core services to third party applications 210 using software that is running on different operating systems and devices, written using different programming languages and tools from multiple vendors, all potentially developed and deployed independently. As a result, an open architecture for third parties is created. Furthermore, web services 222 enable the interactive messaging system of the present invention to be used with or without a browser.

Also located on the application framework 202 is a web application server 230. Web application server 230 includes software that runs on the application framework 202, answers web calls from a mobile device, via web portal 226, and via third party applications 210 and local applications 208. When answering a call, web services 222 looks up the requested information in database 224. The database 224 is used to store data, information and rules for pushing the interactive messages to a wireless mobile device. Specifically stored within the database 224 are user preferences, photographs, sounds, drop-down menus, learning curriculum, birthday anniversary lists and other holidays. Upon receiving a call the web application server 230 retrieves the information in the database 224 via data services 212. FIG. 2 enables users to send various types of interactive messages. The various types of messages include, among other things, scheduling a meeting, sending a reminder, initiating a multi-player game on a wireless device, interactive learning, and biometric authentication messages.

FIG. 3 illustrates system architecture 300 for out-of-band biometric enrollment using interactive messaging, according to an embodiment of the invention. The system architecture 300 includes different components which may dynamically interact with each other through network connections 302. Network connections 302 refer to any suitable connection between computers, such as intranets, local area networks (LAN), virtual private networks (VPN), wireless area networks (WAN), and the Internet, among others readily understood by one of ordinary skill in the art. System architecture 300 includes one or more computing hardware suitable for executing the components within system architecture 300, according to embodiments described herein. Components of system architecture 300 may be executed by a server, a single computer, or multiple computers in a distributed configuration.

System architecture 300 includes one or more service providers 306, one or more identity providers 320. The service provider 306 may be any application (e.g., E-commerce web sites, educational web sites, banks, forums, etc.) that provides services to a client through computing devices 318. The identity provider 320 includes one or more databases 304, one or more biometric engines 100 (such as shown in FIG. 1), and one or more IMS 200 (such as shown in FIG. 2). Biometric engine 100 is operatively coupled to one or more IMS 200, through network connections 302, in order to provide an identity provider infrastructure 320. Identity provider 320 includes a biometric authentication service (BAS 308), which may be within IMS 200 or included as a separated module operatively coupled to IMS 200. BAS 308 is used to facilitate biometric data exchange between senders and receivers. Biometric engine 100 communicates with the IMS 200 by generating web calls to a web application server configured within the IMS 200. The web application server also responds back to web calls generated by biometrics engine 100 based on information stored in a database within IMS 200 that may include rules or logic for answering these calls.

Service provider 306 communicates with identity provider infrastructure 320 through a network connection 302 using authentication protocols 310, such as security assertion markup language (SAML), OpenID, XML, or any other suitable framework for communicating user authentication. Service provider 306 enables users to access services by allowing them to be authenticated by the identity provider 320 infrastructure.

In one embodiment of the invention, authentication protocol 310 may employ a SAML based framework for allowing biometric enrollment between service provider 306 and biometrics engine 100; thus, authentication protocol 310 may allow exchanging user authentication and authorization data of a user 312 to one or more service providers 306. Using SAML, an online service provider 306 may contact a separate online identity provider 320 to authenticate users 312 who are trying to access secure content. SAML protocol, comprising XML-based request and response message formats, may be bound to many different underlying communications and transport protocols; SAML currently defines one binding, to SOAP over HTTP. SAML authorities may use various sources of information, such as external policy stores and assertions that were received as input in requests, in creating their responses. In an SAML scenario, the identity provider 320 asserts the identity of user 312 and the service provider 306 may consume the assertion and pass the identity information to an authentication application.

In another embodiment, authentication protocol 310 may employ an OpenID based framework for allowing biometric enrollment between service provider 306 and biometrics engine 100. Using open source authentication protocol 310 allows the integration of biometrics engine 100 as a plug-in solution to provide biometric authentication to a plurality of service providers 306.

Biometric engine 100, service provider 306, and IMS 200 include a central processing unit run related algorithms or computer executable program instructions that may be executed by a server, a single computer, or multiple computers in a distributed configuration; and may be configured to interact with one or more components of the same or different type operating within system architecture 300. Each central processing unit may include a processor with computer-readable medium, such as a random access memory (RAM) coupled to the processor. Examples of a processor may include a microprocessor, an application specific integrated circuit (ASIC), and a field programmable object array (FPOA), among others.

System architecture 300 allows for one or more computing devices 318, displaying a graphical user interface configured to receive information from the system architecture 300, to request and/or feed information dynamically through the interaction of the computing device 318 with different software modules. Examples of computing device 318 may include desktop computers, laptop computers, tablets, among others.

One or more mobile devices 314 may be operatively coupled with biometric engine 100 and IMS 200 through network connection 302. In other embodiments, such connection may be implemented through 3G, 4G, Wi-Fi, WiMax, and landline broadband, among others.

Mobile devices 314 are used to capture biometrics of user 312. Examples of mobile devices 314 may include smartphones, desktop computers, laptop computers, tablets, and PDAs with a camera, a voice recorder, a fingerprint scanner, and/or other biometric probes 316 capturing components, among others, and any subset thereof. In one embodiment, mobile devices 314 support multimodal biometrics for capturing a plurality of biometric probes 316 including, but not limited to face, fingerprint, iris, and voice, among others, and any subset thereof. Mobile devices 314 submit one or more biometric probes 316 to biometric engine 100 for verification. Biometric engine 100 matches the biometric probe (which may first require converting the probe into a template) against previously stored biometric templates. Matching may result in individual scores for each type of biometric template being compared, for example, one score may be generated for the iris comparison, and another score for the voice comparison. The biometric scores generated for the different modalities of biometric probes 316 may be combined into a single fusion biometric score that can be used for validating the biometric authentication.

One or more clients 312 may enroll their identities through the use of one or more mobile devices 314 in communication with a biometrics engine 100 in the cloud to perform one or more transactions using a computing device 318. A transaction may include one or more users 312 making an online purchase of one or more items or services over the Internet or cloud using one or more computing devices 318. For example, client 312 may enter a website using computing device 318 for making a particular purchase, in which case, that particular website may require biometric authentication. To accomplish the biometric authentication, client 312 needs to perform a biometric enrollment in order to be able to complete a transaction and make a purchase, for example, after swiping a credit card to purchase an item or service in a store.

Service provider 306 requests the enrollment of user 312 before being able to approve any transaction. For example, service provider 306 may be a bank, an online retailer, a cloud-based application, a store, a webpage, or a service company requiring the authentication of user 312 who may be using a credit card for acquiring goods or services.

Client 312 initiates a transaction with a computing device 318 in the cloud through a suitable network connection 302 with service provider 306. Authentication protocol 310 requests user 312 a username, password, and one or more biometric probes 316. Biometric probes 316 may be analyzed by biometrics engine 100 and stored in database 304 to be used in further biometric authentication operations.

IMS 200 sends interactive messages requesting biometric probes 316 to a client's mobile device 314. When receiving the message, the client may respond to the message providing the biometric probes 316 requested. BAS 308 sends the biometric probes 316 to the biometrics engine 100 for biometric matching. The biometrics engine 100 compares biometric probes 316 received by the BAS 308 against biometric templates previously stored in database 304 for the user at enrollment. The biometric matching may yield a score that represents the possibility that the biometric template and the biometric probe 316 are from the same identity. Identity provider 320 sends a response back to a service provider 306 in order to verify if the client has been successfully authenticated.

FIG. 5 illustrates a method 500 for out-of-band biometric enrollment using interactive messaging according to an exemplary embodiment of the invention. Here, a SAML authentication protocol is employed as a gateway to biometric enrollment using mobile interactive push messaging. Method 500 for out-of-band biometric enrollment using interactive messaging may start when a SAML service provider requests 502 to a SAML identity provider for one or more clients' enrollment in order to allow access to the services and/or products offered by the service provider. A service provider can be an online retailer, a cloud-based application, an online banking website, a webpage, a store, or a company requesting a client's enrollment. The identity provider may maintain and manage identity information for clients and may provide authentication to other service providers.

The identity provider may subsequently check 504 if the client information is already included in the list of users within the identity provider's database. If the information is not included within the identity provider's database, service provider requests 506 the user information to subsequently submit 508 the user information to a biometric engine, through the identity provider. If the information is included within the identity provider's database, identity provider submits 508 the client information to the biometric engine, where biometric engine may add 510 the user information within the already existing list of users.

If necessary, biometric engine sends 512 an e-mail or notification to the client with instructions for downloading and using a biometric authentication application. The client employs a mobile device capable of supporting multimodal biometric authentication to download 514 and open the application to perform the identity enrollment. Once the mobile device runs the application, the client employs such device to enter 516 into the application a preferred user name and, if desired, a password. In other embodiments, the client may also include a phone number, address, or any other suitable information that may serve as an identifier.

Once a username has been selected, the application requests to capture 518 one or more biometric probes. The client employs the mobile device to capture 518 one or more biometric probes and subsequently submit the generated information (e.g., username, password, biometric probes, mobile device's ID) to the biometric engine for enrollment.

Biometric engine then enrolls 520 the submitted biometrics into one or more biometric data caches depending of the type of biometric modality; while the username, password, and other identifying information, such as mobile device's ID, are stored in a database within the biometric engine, where such information is associated 522 with the user. A device ID may include a MAC address, a phone number, integrated circuit card identifier (ICCID), or any suitable unique identifier that may allow recognizing and sending interactive messages to the mobile device used to open the authentication application. The SAML identity provider may now identify as valid the enrolled user and the SAML service provider may allow the user to have access to the services and/or products offered.

FIG. 6 illustrates an architecture 600 for out-of-band biometric enrollment using interactive messaging, according to an exemplary embodiment where a web application server 602 uses a mobile access gateway 604 to send to a mobile device 606 an interactive message 608 requesting biometric probes to perform a user enrollment.

The mobile access gateway 604 channels push messages to the appropriate mobile devices 606. The web application server 602 may be included as part of IMS which may in turn include the rules defined by the sender for pushing the interactive messages to mobile devices 606. The interactive message 608 notifies the user about the new security policy that has been applied and request to store biometrics probes for a future log in session to the service provider that the user is trying to access.

Interactive message 608 is designed using different configurations which may be based on information stored in the IMS related to the user of the device, service provider preferences, user preferences, security level, modalities supported by the mobile device, modalities supported by a biometrics engine, etc. In the illustrated example embodiment, the web application server 602 determines that mobile device 606 supports a face recognition biometric modality. Interactive message 608 may then include the option to take a picture using a camera from the mobile device 606.

EXAMPLE #1

The following provides an example application of the disclosed method 500 for out-of-band biometric enrollment using interactive messaging where a related enrollment process may be performed by system architecture 300 to access a service provider. In this example, a user used to log in with username and password credentials. However, the service provider may have implemented biometric authentication into the security policy for protecting the user's identity and enhancing security.

As seen in FIG. 6, the service provider's web application server 602 employs a mobile access gateway 604 to communicate with a mobile device 606 and send an interactive message 608, which contains a request to submit one biometric probe to proceed with the user enrollment employing biometric authentication. The interactive message 608 provides options to select one type of biometric probe 610 from which the user selects to provide a fingerprint from the options provided. After capturing the fingerprint, the user selects the option to send the biometric probe and the generated data is sent to the web application server 602. The web application server 602 then associates the captured biometric probe with the user profile and the device employed to log in, while a biometric engine may convert the biometric probe(s) into corresponding biometric template(s) which can be stored in one or more data caches.

In a next log in session, the user can provide a biometric probe to be verified or identified against stored templates, thereby, allowing access to the service provider.

FIG. 7 illustrates a method 700 for out-of-band biometric verification using interactive messaging according to an exemplary embodiment of the invention. At step 702, a service provider requests a user for verification to the identity provider. The request may be generated using authentication protocols calls such as, but not limited to SAML, OpenId, SSO, or others, the identification and implementation of which are apparent to one of ordinary skill in the art. In one embodiment, the request call includes information related to the user, such as name, username, password, email, login name, phone, etc. At step 704, a determination is made to verify if a service provider has provided enough user information for biometric verification. If enough user information has been provided, a request for biometric verification is submitted to a biometric engine (step 706). If user information is not included in the request or it is insufficient for verification, the system captures and submits the user information (step 708) from cookies, a log in screen or any user information source. The biometric engine and interactive messaging system then use the information provided to search for a wireless mobile device associated to that user in a database of enrolled users (step 710). For example, the interactive messaging system searches for the phone number associated with the user information in order to push a message to the wireless mobile device. The interactive messaging system then pushes a verification message (step 712) to the device of the user requesting biometric input. Upon receiving a message requesting biometric input, the user uses any available biometric capturing modality enabled by the wireless mobile device to capture a biometric probe (step 714). For example, a user uses a microphone from a wireless mobile device in order to provide a voice biometric probe. The user may then respond back to the biometric request and send a biometric probe for biometric verification (step 716). The interactive messaging system then receives the response to the push message sent and sends the biometric probe captured by the user to the biometric engine for biometric verification. In step 718, the biometric engine compares the received biometric probe against the original biometric templates stored for that user at enrollment. The comparison yields a score that is used to determine if both the biometric probe and the biometric template belong to the same person. A response is created and sent to the service provider which includes the results of the matching process (step 720). The service provider may then grant or deny access or services to the user depending on the result (step 722).
